After a three-month engagement, Adam and Leighton have tied the knot! ‘The O.C.’ alum and the ‘Gossip Girl’ made it official, according to multiple reports!

Adam Brody & Leighton Meester Married

The actors met on the set of The Oranges in 2011, then starred again in Life Partners in 2013. Over the weekend, Adam, 34, was seen out at LAX and had a gold band on his wedding finger. Meanwhile, Leighton has been working on her Broadway show with James Franco, Of Mice & Men.

They were spotted together at St. Regis Punta Mita Resort in Mexico from Feb. 12-15 — and a few weeks before that she headed to West Hollywood for her Bachelorette party!

Clearly, Josh Schwartz — the creator of both The O.C. and Gossip Girl — officiated the wedding. Ok, we don’t know if that’s true yet, but we know that it must have been a lavish affair. We’re hoping both Blake Lively and Benjamin McKenzie were there for the ceremony.

Sounds like third time’s the charm for Leighton, 27. (Ok, so this is actually her first wedding, but on the show her character was married twice!)

There are no details revealed yet, and HollywoodLife.com have reached out to reps for both stars.

We’re so excited for these two! Are you surprised they’ve already gotten married? What do you think? Let us know!
